ABSTRACT:
An aircraft secondary power system having a selectively operable power source for drive of accessories and for starting of a jet engine. The system includes a clutch which is engaged when the power source is to start the engine. At a predetermined engine speed, the engine takes over the drive of the accessories through the clutch and, at a selected higher speed of the engine, the clutch is disengaged to cause the drive of the accessories from the engine at a lower drive ratio whereby the accessories are driven at a lower speed relative to the speed of the engine.
